The Águas Livres Aqueduct is a historic aqueduct in the city of Lisbon, Portugal. It is one of the most remarkable examples of 18th-century Portuguese engineering. The main course of the aqueduct covers 18 km, but the whole network of canals reaches nearly 58 km.
Lisbon had always suffered from a lack of drinking water. Thus, King John V decided to build an aqueduct to bring water from sources in the parish of Caneças, in the modern municipality of Odivelas. The project was paid for by a sales tax on beef, olive oil, wine, and other products.
